Abstract
A sensing system adapted to determine changes in phase when a capacitive object enters into the phase detection zone created by a pair of transmitting conductors. One of the transmitting conductors has a receiving conductor located proximate to it and transmits a signal at a certain frequency. The other transmitting conductor transmits a signal that is phase shifted from the signal transmitted by the other transmitting conductor. Capacitive objects entering the space between the two transmitting conductors impacts the phase. Measurements of the change in phase are used to determine the position of an object between the two transmitting conductors.
